That ^^^^ is why club's like St. Louis' have suffered in past years. No unity. Our club's league has a great reputation, look at the growth. I understand the need for some league division, due to logistics, but I think that we need to keep some of the core there.
I think that separating singles and doubles on different nights won't solve the numbers issue we had with doubles. They were separated already, just by the time of the summer. I do however believe that having a singles option (like Shane's handicap league) available on the same night as the doubles will reduce the overflow we saw during doubles early last summer.
As far as invading courses, ball golf leagues do this too. Post league schedules on all the course's message boards, so the information is available to the rec players, it's not like there's nowhere else to play. Plus, I think that it's good for rec players to come to a course and see the numbers we had out there, it might encourage them to join the league, or inspire them to start playing on a more competitive level. We're trying to grow our sport, right?
I also think that it wouldn't be a bad idea to include courses like Ankeny's, Newton's and Ames' into our schedule. We go to Indianola once or twice, why not eliminate a few of the rounds at GV for some of these other gems that we have access to?
